try this

for file in `ls |awk -F"." '{print $1}'|uniq -c | awk '+$1 == 3' | grep -x 3 | awk '{ print $2 }'`
do
    mv $file.* targetdir
done

The lines with three extensions are already selected by the awk, so you don't need the "grep -x" command.

for file in `ls |awk -F"." '{print $1}'|uniq -c | awk '+$1 == 3{print $2}'`
do
    mv $file.* targetdir
done

The grep is based on posted output:


3    file01
3    file02
2    file03

Yes, remove the "grep -x 3" - the "-x" matches an entire line, and since none of the lines contain just a "3", none match.

@omarfarid - it was confusing, but the posted output was of the command up to the "uniq -c" - it didn't include the "awk '+$1 == 3'" bit.

for f in $(ls |awk -F"." '{print $1}'|uniq -c|awk '$1==3 {print $2}')
do
   echo "Moving files starting with $f"
   mv $f*  /some/dir
done

Open in new window

One small comment on the accepted answer - you need the dot after the filename in the "mv" command (as I had in my answer #a40003432)
for file in `ls |awk -F"." '{print $1}'|uniq -c | awk '+$1 == 3{print $2}'`
do
    mv $file.* targetdir
done

Open in new window

If you have, for example:
    file1.ext1
    file1.ext2
    file1.ext3
    file10.ext
in your input directory, the accepted answer would copy the file10.ext1 file, because it matched "file1*", even though there was only one file with the file10 prefix.
